The White-Rodgers Classic 80 Series™ thermostat uses the technology of a solid-state microcomputer to provide precise temperature control. If youâ€™re in the process of upgrading a multi-stage, heat pump or single stage system, donâ€™t forget the â€œbrainâ€ for your new systemâ€¦your thermostat. Our White-Rodgers 80 Series can maintain a set temperature to within one degree. Plus, thereâ€™s a permanent memory that saves all programs and settings during a power loss.
